The present invention comprises modifications of that described andillustrated in my pending application, Serial Number 19,390, filed May2, 1935, patented March 9, 1937, Patent No. 2,073,-

9 139, for improvements in an Apparatus for treat ing steamheating-systems. Y

The invention and its modifications will be more fully described in theaccompanying specification and drawing in which:-+

'10 The drawing shows a side view partly in sec-- tion and partly inelevation of a compound heating and injecting installation embodying myinvention.

In the drawing, the line 4| leads directly into the compartment 42 at alow point thereofior the purpose of discharging steam under pressuretherein. Said line 4| is provided with a shut-oil valve 42 which may beclosed to allow thepassage of steam through the horizontal line M, whichis coupled to line 4| by means 01' T- A connection 45 and which has ashut-oi! valve 46 interposed therein adjacent to line. Line 41communicating with the container 42 at 48 thereor provides means ofegress for the steam and 25 compound mixture and is joined to line 44 bymeans of the T-connection 49. On the low side 01' said T-connectlon 49the line 44 has interposed therein the check valve 50 and leads to themain line 5! by means of the T-connection 52. A line 30 as is coupled tothe main line 5| by means of the T-connectlon 54 and communicatesdirectly with the coil 55 in container 42. Various elbows i9 and unions51 are interposed in the lines where they are necessary.

35 In use, this apparatus is capable oi two modw (cl. ctr-i) ofoperation. If the valve 46 be turned oil with the valve at open, thesteam under pressure will, enter the container by means of line H andwill force compound 88 into the main line bi by means at line W,T-connection 49 and line M. b

The other method may be employed by closing valve 49 and opening valveib whereupon the steam will pass through line 4t, the T-connection 49,the check valve 64 and back into line 9i by means of coupling 52 and inso doing will convert 1 the line 41' into a siphoning tube,-drawing themixture by this means into the main line ti. As in the first form of theinvention, a heating coil is employed to pre-heat the treating solutionand this may be coupled to either the high or low 5 I side of the mainline.

The device is capable of various modifications in structurev and designwithout departing from the spirit of the invention, all within the scopeof the appended claim. 7 20 1 Having thus described my invention, what Iclaim as new and desire to secure by Letters Patent oi the UnitedStates, is:-

In combination with a steam heating system having a reducing valvetherein, a container for 25 pipe treating compound, a line from the highpressure side oi the valve communicating with the container, a heatingcoil in said container, a line from the low pressure side of said valvecoupled with'the coil, and a discharge line leading 30 from saidcontainer to the heating system whereby the compound will be forced intothe pipes thereof.
